CHARLES W. NEWTON, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOJE] MACHINERY CORPORATION, OF BATEJRSON, JERSEY, A CORPORATION OF new JERSEY.

vAMr-rnnronarme MACHINE.

Application filed September 23, 1920. Serial No. 412,126.

To all whom it may concern:

Beitknown that I, CHARLES NEWTON, I

5' of Massachusetts, have invented certain Improvements in Vamp-Perforating Ma chines, of'which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.-

v This invention relates to machines for operating on sheet material and is herein shown as embodied in a machine for perforating Vamps.

In the manufacture of boots and shoes, it is usual to. ornament certain parts of the upper by punching designs therein by means of a gang punch. When it is desired so to use a pattern punch to ornament some shoe parts, as the toe. portion of a vamp on a wing tip, difiiculty is encountered in presenting the work to the machine in the proper manner for the reasonthat the toe portions of Vamps are not symmetrical, and their outlines differ according as they are rights or lefts and according-to their sizes. Moreover, the longitudinal position of the design to be punched varies, its distance from the center of the throat of the vamp'varying in different styles ofshoes. Again, the pattern punches varv, the perforating tubes being located at 'difierent distances from the edges of the dies. Furthermore, whena vamp is to be provided with a line of perforations, or with an ornamental medallion, it is often desirable to angle the design, that is, ,to place that portion of the design on the outer-side of the shoe slightly rearward vof that portion on the inner side. On rightand left shoes this displacement of the design-is equal and in. opposite directions.

An object of the invention, therefore, is

to provide a satisfactory mechanism for positioning vamps to be perforated and so aconstructedthat it'may be efi'ectively utilized to position vam 'ps or wing tips of different styles with respect to various perforating or other ornamenting mechanism under the varying conditions existing in difl 'erentfactories and' of such a, nature that it will jp'ermitthe' operator to-work a t' a maximum speed with a minimum possibility of error.

With this objectvin view, there is provided in the illustrated machines, in combinaton, a cutting'block, a perforating die for ornamenting a vam and a vamp support connected to the'dle and movable with respect to the cutting block to carry the vamp from a vamp posltioning to a vamp perforating position. Features ofthe invention include also, means for adjusting the vamp angularly to position the ornamentation at an angle to the center line of the vamp and means for taking care of variations in the style of vamp or the die.

Although the term vamp has been used repeatedly throughout the specification and claims, that term has been used merely for convenience and is intended to cover, where the context and prior art permit, not only Vamps, but wing tips or other parts of shoes to be ornamented. Although the invention has been illustrated as being in the nature of an attachment for existing machines, it should be understood that it is in no way limited in that respect.

Referring to the drawings:

tachable connection between the die and orm of perforating machine together central section V 50 j j J v A 46 by which they may be moved. Each In the embodiment shown in Figs. 1 to 8, the punch and vamp gage are secured together ,for joint sliding movement toward 1 and from the die block. At 8 is indicated the usual cutting block or bed over which is fed the paper backing strip 10 and, be-

plate 26 which is yieldin y mounted and 20 buttons 24 for holding the work; In place of the usual edge gage which projects above the stripper plate I have rovided a filler comes flush with the top ace of the stripper plate. The die or' punch is inserted beneath the die block, with its toe end towards the rear, this being the reverse of the usual arrangement.

' In the form of the invention shown particularly in Fig. 1, the vamp is first placed inthe' desired position. on a carrier while it is free and clear of the cutting block.

The vamp carrier and the die aresec'ured together, and, when the vampis positioned, all these members are moved rearwardly to a punching position. For this purpose,

' there is bolted to the frame of the machine,

I a pair of inclined guide bars 30, on which slides a'skeleton slide block 32 which, with the attached parts, constitutes the vamp carrier. Suitable guide lugs 34 projecting,

downwardly from the slide block 32 direct its movement toward the punch. As the style of die or punch is frequently changed, it is desirable to have the die detachably connected tov the vamp carrier and gage.

As. shown in Fig. 8, this detachable connection consists of headed screws 36 projecting fromthe die holder12 and adapted to enter apertures 40 formed in lugs 38 on the {rear of the slide block '32. To look these parts in position, there are provided 'lock plates 44 slidably mounted in guides 42 on the block' and having, finger pieces lock plate 44 is provided-with anv aperture I a narrow slot; so that upon sliding' the plate, I

of the size of the aperture 40 and also with it will engage bhind the head of the screw 36 to secure the die and vamp carrier together. A stop 48 may be'used to indirate when the apertures are in registration.

-. from the edges ofthe dies.

In the, various styles of dies the unches arev frequently fixed at different distances It is therefore esirable to have an initial adj'ilstment of t e diewithre ference to the vamp sup port, and gage. ,For this reason the slide block 32 is provided 'with a cut out portion I 50, and, moving inways 54 of the slide block, and in the cut out portion, is a slide member 52 carrying the vamp support and gage. The slide member has a vertical flange 56 at its front end (Fig. 4), this flange having slots for guided movement.

along the ways 54. Attached to an inter- 'med1ate portion.of the slide member 52 by means of a screw 60, (see Figs. 3 and 5) is a bar 58 forked at its ends and having pointers or indices 62 for. co-operation with scales 64 on the face plates 66 of the block.

1 These scales 64 are graduated in accordance with a characteristic of the die and are marked .by numbers which may be placed along the scales, these numbers correspond" ing to similar numbers which may be stamped on the different dies.

For securing the slide member 52 to an operating means after the initial adjustment has been made,'there is provided a pivot screw 68, which is threaded upwardly into the member 52, and a bushing, consisting of a reduced portion 74 which slides in a' slot 70 of the block 32 and of an enlarged shouldered portion 76, to which isclamped a link'80. -This link' is slotted, as indicated .at 78, and a clamp 'nut- 82, threaded on the bushing, secures the link to the slide member 52. The bushing is loosely swiveled on the pivot screw 68 so that there is provision for swinging movement of the link.

The link is connected at its other end to an operating leverthrough the following grade adjusting connections. At the end of the link is a pivot84'secured to an adjustable block 86 mounted .to slide in a groove of the arm 88 pivoted at 90 to the slide block. The block 86 has an indicator or pointer 94 for co-operation with a scale on the arm 88 and a clamp screw 92 holds the block in adjusted position. This last adjustment is to provide for the varying of the grade as it. is called and it is not necessarily used slnce the s'1ze variations are quite generally standardlz'ed. If a different system ofzsize measurement is used, however, the placing of the pivot 84 nearer to or farther from the pivot 90 will alter the throw of the link and the vamp gage to which it is connected. After the preliminary adjustments have been made, 'the vamps are' progressively positioned and punched throughout the series of,sizes, as described hereinafter, the lever 98 being ,nioved over .a sector-sha e member having a -'scale 100' with size in ications thereon.

Since to permitthenormal functioning of the stripper plate,'the work and its supporting means must .give alittle, the gage plate 116 whlch carries the vamp positionlng me'ans,1s mounted to have pivotal movement about the pivot screws 108 (Fig.i2

These screwsj 108 are'carried by amemberL' 1121 having interposed between it sand the plate 116 is mounted for sliding movement in Ways 114 carried by the member 112 and a scale 140 on the gage plate.

has at its front end, a lug 118 for locating the throat of the vamp and, at its other end,-a slot, on the sides of which are grad.- uated scales 120. A suitable clamping blodk 124, having pointers 126 for co-operation with these scales, 1 is slidably mounted in the slot and has a clamping screw 122 threaded in the member 112 to hold the gage plate 116 in adjusted position. justment is provided to take care of the differences in the styles of Vamps, as for instance, Where there is a variation in the dis- "tance of the perforations from the throat of the vamp.

In punching the vamp, it is often desirable toangle the perforations with respect to the vamp center line. For this purpose,

p the gage plate 116 has'a series of are shaped guide slots or ways 130 (see Fig. 7), in which is mounted a guide plate 132 having arcuate guide projections 134. The slots and projections are curved about a center at the Ing -118 so that the vamp will be moved angularly about its throat'as a center. Guide washers 136 may be secured to the projections to prevent the escape of the guide plate. To indicate the extent of the angular movement, there is attached to the guide plate, a pointer 138 for co-operation with To effect this angular adjustment, an extension 142 of the guide plate may be swung to the right or left by a clamp screw 144 passing through an arc shaped slot 146 in the gage plate.

For supporting the vamp as it turns through this angle there 'is attached to the guide plate at 1.52 by. means of screws a vamp supporting 'plate 150. This plate 150 may have parallelnumbered lines to aid in positioning a so-called circular or short vamp if such work is to be punched. Secured to the guide plate 132 is a rear set of V-arms or gage members 154 mounted to swing about the pivot 156. These arms are constrained to move equally with reference to the vamp center line by means of links 158 pivoted at one end to the arms and being pivoted at their opposite ends to a pin 160 sliding in a slot 162 on the guide plate. Attached by means of the pivot 166'to the vamp supporting plate 150 is a forward set of V-arms or gage members 164. These arms are connected pivotally to links 168 which, in turn,

vare secured to a pin 170 sliding in a'slot 172 This ad-- .of the vamp carrier and die.

In operation, the desired die is first selected and secured to the carrier by the connection shown in Fig. 8. The parts are then placed in the position shown in Figs. 1 and 6 and the vamp positioned around the gage arms with its throat against the lug 118. The initial adjustment to 'compensate for the style of die is made by loosening the nut 82 and moving the slide member 52 until the. indicator 62 comes opposite the desired number on the scale 64. This number is obtained either from the die or from a die schedule with which the operator is furnished. The nut 82 is then tightened to clamp the slide member 52 to its operating means. The initial adjustment to compensate for the style of vamp is made by loosening the clamp screw 122 and moving the gage plate 116 in the ways 114u1itil the pointer on the block 124 is opposite the desired number on the scale 120. This num-- ber is obtained from the work ticket and determines the distance of the perforations from the throat of the vamp. The clamp screw--122 is then tightened to secure the gage plate to the member 112 an'd'slide member52.

To center the vamp, the gage arms 154 and 164 are spread apart until both sets tightened and the lever98-moved along the.

size scale 100 to the number corresponding to the size of the vamp. The connected die and vamp carrier are then slid down the guide bars 30 as far as they will go whereupon the cutting block 8 is caused to descend to perforate the work; When the die and carrier are again moved forwardly, the vamp of the next size is selected and positioned, the only correction thereafter necessary for the progressive punching of the Vamps being' the swinging of the lever 98 along its scale in accordance with the size.

In Figs. 9. to 13 inclusive, I have shown another form of perforating machine and'a modified form of vamp gage. The perforating die is not mounted to slide as in the other form. In these figures I have indicated parts corresponding to those in the other form of -my invention by means of reference numerals having an additional-200.

In this machine-there is provided a cutting block 208 for co-operation with a punch plate 218' and a stripper plate 222; At-

tached to a bracket 230' on the frame is a block 232 secured in place by means of suitable clamp screws 234 and 236. Mounted adjustably in ways 254 in theblock 232 is a slide member 252, the position of this slide member being indicated by a scale 264 011 10 the block 232. This scale co-operates with an index 262 on the slide member andthe adjustment is toprovide for the style of.

Around this pivot is swiveled a bushing comprising a portion 274 reduced. to slide in the slot 270 and anenlarged shouldered portion .276 for clamping engagement with a slot 278 in a link 280. The link is pivotally connected at 284 with an operating lever 298 which, in turn, is pivoted to the block sizes, is arranged for co-operation with'tlie lever 298. I

Mounted in ways 314 in the slide member 252 is a gage plate 316 from which extends a dove-tailed slide tongue 317. The sliding movement is provided to give an adjustment in accordance with the style of vamp and the adjustment is indicated preferably by a scale 320 on the sides of the slide member 252. The scale and index may be reversed, if desired and the parts may be secured together by a clamp screw-322 threaded in the gage plate 316 and abutting the member 252. For angling the vamp 'to the right and left to place the ornamentation at an angle to the center line, the following mechanism is utilized: The gage plate 316 has arcuate guide slots 330 in which are mounted arcu- .ate guide plates 332 secured by the screws v 352 'to a vamp supporting plate 350. The amount of angular movement. is indicated by :means of a pointer 338 on the supporting plate co-operating'withja scale 340 onthe gage plate 316. The supporting plate 350 :may be clamped in adjusted position by means of a clamp screw 344 threaded in the gage plate 316 ,and passing through an arcshaped slot 346 in the supporting plate.

Y of the vamp to-center the latter on the supporting plate, there, are provided frontand rear sets of gage arms. The rear set com prisesarms' 354 pivoted at 356 and constrained to move together by means'o'f ,the links 358. Theselinks are pivotedv at their meetingends to a slide block 362 mounted fto move in a slot in the supporting plate. similar set of front gage arms 364. are

232 at 290. A scale 300, graduated 1n vamp means of an index 326 on the tongue-317 and to place the perforations at .center line of the vamp.

pivoted at 366 and connected togetherby means of links 368 pivoted at 37 0 to a block 372 slidingin' a slot in the supporting plate. To position the throat of the'vamp, there is secured to the .plate 350 a bracket 374 to which is pivoted a member 376, this member. being held normally in a slightly raised position above the stripper 222- by means of a spring 378. This spring allows the memher to yield under punching pressure.

In the operation of this modified form, the preliminary adjustments to compensate for the different styles of dies and for the different styles of vamps are made in a manner similarto that described with reference to'Figs. 1 'to 8. The vamp is centered on its supporting plate 350 by means of the throat engaging member and the gage arms. If the vamp is to be angled, the clamp screw is loosened andthe supporting plate swung to the right or left to the desired extent indicated by the scale 340. The toe portion of the vamp then projects rearwardly the proper distance between the die and cutting block to receive the perforations. The progressive punching of the Vamps is then continued throughout the series of sizes, by successive adjustments of the lever 298 over the size Scale 360.

Having thus described my invention, what I claim as new and desire to secure byv [Letters Patent of the United States is die, and means to adjust the positioning means angularly to, position the perforations at an angle with respect to the center line of the vamp. 1 2.
